TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 501,977, dated July 25, 1893.

Application filed December 2, 1891. Serial No. 413,756. (No model.)

To @ZZ whom it may concern:

Be it known that I, GEORGE B. VEBB, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

My invention relates to means for facilitating tabulated or column work, and has for its principal object to maintain control of the paper-carriage, when released for rapid advancement to a column stop, so as to avoid the shock and jar heretofore occasioned by the sudden arresting of the paper-carriage by contact with the column-stop.

My invention has for further objects simplicity of construction, arrangement, and operation, and consists of the features of construction and eombinationsof devices hereinafter more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a plan view of the Remington paper-carriage (stripped of its platen,` platen-carrier, paper-feeding mechanism, &c.), the guide and hinge-rail, and the usual shift-rail for the platen-frame or carriage, and showing also my present improvements. Fig. 2 is an elevation of the same taken at the left-hand end of the machine, with the top plate added. Fig. 3 is a front elevation of the same. Fig. 4 is a partial plan view of a modification of my invention, and Fig. 5 is a front elevation similar to Fig. 3, but showing the modified construction.

In the several views the same part will be found designated by the same numeral of reference.

1 designates the posts or pillars and 2 the top-plate of the Remington machine.

3 is the main carriage hinged by eyes 4 upon the guide-rail 5, and provided with grooved wheels 6 which run upon said rail.

A frame 7 is also hinged upon said rail and provided with a feed-rack 8 with which cooperates as usual the letter spacing dogs 9.

Attached to said hinged frame 7 is anarm 10 which is bent to pass over the rail 5 and extended forward to terminate contiguous to the rear end of the left hand side bar of the carriage. In bearings 11 on the outer side of said side bar is mounted a rock-shaft 12,Which at its rear end is bent inwardlyunder the said side bar to provide an arm 12, which rests upon the forwardly extending arm 10. Near the front end of the rock-shaft is secured a finger-piece or key 13 which projects upwardly and inwardly over the said side bar of the carriage.

14 -is an arm or lever formed at one end with an eye or bearing 15 which is fitted upon the prolonged front end of the rock-shaft. Made integral with said eye or bearing is a projection or finger 16, which rests against the outer side of the upwardly extending portion of the finger-piece or key 13.

At or near the inner end of the arm or lever 14 is a dog, tooth or projection 17, and a finger-piece 18, while between the ends of the arm or lever is a spring 19, acting to keep the lever in a raised position.`

Beneath the carriage is a rod, 20, preferably secured at its ends to blocks or supports 21, having pins or dowels 22 which fit detachably into holes in the top-plate, so that the rod may be removed when not wanted. The rod 20, is provided with a series of perforations 23, adapted to receive a series of removable or adjustable pins or stops 24. The perforations or holes 23 are arranged apart or graduatedto correspond with the divisions of the machine scale 25. Preferably, however, there is only one hole to every live degrecs of the scale, as this `arrangement has been found in practice to be ample. The holes are preferably numbered as shown to aid in facilitating the work. At Fig. 3 of the drawings, two pins or stops 24 are shown, one at the hole 20 and the other at the hole 40 of the stop-rod.

The lower end of the projection or dog 17 stands in a plane slightly above the tops of the pins or stops 24, in the normal condition of the arm or lever 14, so that in doing ordinary work the dog 17 may pass freely over or by said pins. By depressing said arm or lever and holding it down the dog may however engage with said pins upon arriving thereat and by such engagement or contact arrest the carriage. The pointer 26, attached at the axis of the front supporting roller 27 IOO of the carriage, shows at Fig. 3, that the carriage has arrived at 30 on vthe machine scale. If it be desired now to have the carriage move quickly to the point 40 on the scale (sothat a column ot figures may be commenced, for example) the dog 17 is depressed by bearing down upon the lever or its fingerpiece. By this movement the projection or finger 16, acting as an arm of said lever and upon or against the finger-piece of the rockshaftoperates to turn said rock-shaft and cause its inner arm 12 to depress the arm 10 of the hinge-frame and lift the rack-bar S from engagement with the spacing-dogs 9. As soon as this is accomplished the drivingspring or power (not shown), but which may be of any known or suitable construction) acts to propel or pull the carriage rapidly toward the left until the dog 17 strikes or abuts against the stop orpin 24. The pressu re upon the lever 14 may then be released and its spring will return it to normal position. After the carriage has been thus' arrested, and the dog permitted to return to its initial position, the Writing may be proceeded with to the full-limit of travel of the carriage, as in the arrangement exhibited there is no pin or stop in place beyond that at the hole numbered 40.

When the lever 14 is released the rack and rock-shaft are restored to their normal positions by reason of the superior weight of the hinged-frame, which is sufficient through the rock-shaft, to return the lever 14 to its rst position without the aid of the spring 19, which is employed principally to keep the lever up when the rockshaft alone is actuated.

The rock-shaft or lever is usually designated a release-key. This release-key may be operatedindependently of the key or leverl 14, for releasing the carriage in ordinary work and when so operated the key or lever 14 remains in its normalposition by the contact of the shank 28 of its finger-piece with the depending portion 29 of the carriage-frame.

Referring to Figs. 4 and 5, it will be observed tirst, that the usual Remington shift rail, 30, for the platen-carrier is employed also as a stop-rod, and secondly that the key or lever 14 and the rock-shaft of the releasingmechanism are made integral or continuous. The shift-rail is provided with holes or perforations and pins or stops similar to those of the rod 20.

The finger-piece 13 of the rock-shaft is dispensed with at Figs. 4 and 5 and the outer end of the key or lever 14 is connected to or made integral with the forward end of said rock-shaft. By depressing said key or lever 14, the hinged frame is elevated, the carriage released, and the dog 17 -moved down to engage with the pin or stop. 24.

In the construction shown at Figs. 1, 2,and 3, the release-.key may be operated independently of the column-stop key and for this reason in doing ordinary work the pins or stops, although not in use, may remain in the holes in their bar or support without interfering in any manner with the' usual feed or movement of the carriage.

In the construction shown at Figs. 4 and 5, since the release-key is operated through the columnstop key, the pins or stops should be removed when column or tabulated work is not desired.

W'hile I have shown in each case only two pins or stops there may be as many and they may be as variously set as the exigencies of the work may call for.

In all of the views it will be observed that the column-stop key is connected to the carriage and that when actuated to move the dog 17 to working position, serves to operate the carriage releasing devices. And it will be further observed that when the dog 17 is depressed and the carriage released the hand is upon the column stop key (or the carriage) and hence the movement of the carriage toward the lett under the force of its driving spring may be so regulated or controlled as that the carriage may be stopped easily, without shock, when the dog comes into contact with the pin, instead of violently as heretofore, Where the means for moving the dog into a position for engagement with the pin were disconnected from the carriage.

Without departing from the main features of my invention, any of the known forms of release-keys and any ot the known forms of column-stops may be employed.

What I claim as new, and desire to secure by Letters Patent, is.-

1. In a type-writing machine, the comb-ina.- tion with a paper carriage, of one or more relatively tixed or stationary column stops, and a dog connected to the paper carriage and adapted to be moved to engage the column stop or stops.

2. In a typewriting machine, the combination with a paper-carriage and its releasing mechanism, of one or more column-stops, and a key connected to the paper-carriageV and carrying a dog to engage said stop o'r stops.

3. In a typewriting machine, the combina-l tion with a paper-carriage and its releasing mechanism, of one or more column-stops, and a pivoted arm or lever connected to the papercarriage and carrying a stop-dog.

4. In a typewriting machine, the combination with a paper-carriage and its releasing mechanism, of a column stop key mounted on the paper-carriage, and one or more column stops fixed relatively to the paper-carriage.

5. In a typewriting machine, the .combination with a paper-carriage and its releasing mechanism, of a depressible dog connected to the paper-carriage, and one or more column stops connected to the machine frame.

6. In a typewriting machine, the combination with a papercarriage and its releasing mechanism, of one or more column stops, and a column stop key connected to the paper-car- -riage and arranged in proximity to the carriage release key.
